Ristretto JIT
Overview
Ristretto JIT provides a Just-In-Time compiler for the Ristretto VM. The JIT compiler generates native code from Ristretto VM bytecode, allowing for high-performance execution directly on the host machine.
Architecture
The JIT compiler follows a multi-stage compilation pipeline:
- Bytecode Analysis - Analyzes Java bytecode for control flow patterns
- Control Flow Graph Construction - Builds a block based control flow graph
- SSA Transformation - Converts stack-based operations to Static Single Assignment form
- Native Code Generation - Generates optimized machine code
- Function Binding - Creates callable native functions
Features
- Fast execution through native code generation
- Automatic optimization of bytecode patterns
- Control flow graph analysis for complex branching logic
- Platform-specific compilation for x86-64, aarch64 (ARM64), s390x (IBM Z) and riscv64
- Comprehensive error handling with detailed error messages
Platform Support
The JIT compiler automatically adapts to the target platform:
- Native platforms:
- x86-64 (Intel/AMD 64-bit)
- aarch64 (ARM 64-bit)
- s390x (IBM Z Architecture)
- riscv64 (RISC-V 64-bit)
Limitations
Current limitations include:
- Only static methods and constructors (
<init>) are supported - Limited object-oriented features (no instance method compilation yet)
- No garbage collection integration
- Exception handling is not fully implemented
